PRODUCT DESCRIPTION

The DIGIPOINT is an easy to use, dual channel Digital Acoustic Fault Locator, designed by TII. It is used in conjunction with a Surge Generator to determine the exact position of faults in underground power cables. The instrument also indicates the cable by sensing and amplifying the electromagnetic signals produced at the time of surges. The DIGIPOINT consists of two units the Acoustic transducer or pick up and the amplifier unit with head phones.
The unique feature of DIGIPOINT provides a relative distance indicator with digital coincidence figure readout. This feature is very helpful for the operator in pinpointing the exact location of fault.

Applications

For pin-pointing of cable faults DIGIPOINT is used with the headphone and Surge Generator (T-1004,T-1005,T-1020,T-1032). The Surge Generators are devices used for precise location of faults in power cables with the acoustic method. This method provides for the charging of a capacitor with the pulse voltage which is then downloaded to the cable fault through a spark gap.

With the use of the detector, as well as the acoustic is also measured the time between the arrival of the magnetic wave and the sound. Therefore approaching the fault point to the time difference becomes progressively smaller until reaching a minimum value above the fault.

The main parameters detected by the detector are:

Relative distance from the magnetic and acoustic fault in ms. The lower the value the closer the fault.

· Intensity of the magnetic signal present at the location to confirm the presence of the cable and its location.

· Confirmation of the acoustic signal.

· Confirmation of the magnetic signal.

Techno established in the year 1987 is leading organization engaged in manufacturing and exporting of power cable fault locating instruments. Cable fault locator is used for tracing the route and finding faults in underground cables in several power generation, transmission and regulation applications.
